Alcohol, denatured

Guaiacol has a very characteristic odour and burning taste its medicinal properties are identical with those of creosote. Used in the preparation of vanillin and paparvarin and for denaturing alcohol. 

Added 100 grams denatured alcohol, no layer formed as the oily product is miscible in ethanol. Added 20 grams of C//-/2O. This pulled the ethanol and other product into the top layer, bottom layer containing some ethanol and safrole. Separated layers, placed the oily bottom layer into a 2-liter breaker. Took the temp right to 234 C. The ethanol and water came off <=100 C... The safrole started to boil 232C, then came to a full boll and maintained 234 C. Product ui/as yellow orange in color, suitable for whatever purpose one has in mind BTW, after the safrole cooled, she checked it with a 5% NaOH solution to see if any eugenol ivas left behind, no participate formed. 

What are some of the alternatives for this procedure Well, one can use NaOH (lye) in place of KOH but the yields will go down. Also, what about using denatured alcohol instead of pure ethanol Denatured alcohol is ethanol contaminated with 5-10% methanol. The methanol is there because it is poisonous and prevents people from using the ethanol for drinking. This means that places like the giant hardware stores can carry gallons of cheap contaminated ethanol as many of you have discovered. This product CAN be used. 

Miscellaneous Derivatives. Other derivatives of toluene, none of which is estimated to consume more than ca 3000 t (10 gal) of toluene aimuaHy, are mono- and dinitrotoluene hydrogenated to amines ben2otrich1 oride and chlorotoluene, both used as dye intermediates / 7-butylben2oic acid from / 7-butyltoluene, used as a resin modifier dodecyltoluene converted to a ben2yl quaternary ammonium salt for use as a germicide and biphenyl, obtained as by-product during demethylation, used in specialty chemicals. Toluene is also used as a denaturant in specially denatured alcohol (SDA) formulas 2-B and 12-A. 

The primary producers of ethyl alcohol also market the specially denatured and completely denatured alcohols, as well as various proprietary solvents in which ethyl alcohol is the basic ingredient. These various products can also be described by rigid and descriptive specifications, but the... 

Denatured Ethanol. Eor hundreds of years alcohoHc beverages have been taxed all over the world to generate government revenue. When ethanol emerged as a key industrial raw material, the alcohol tax was recognized as a burden to many essential manufacturing industries. To lift this burden, the Tax-Eree Industrial and Denatured Alcohol Act of 1906 was passed in the United States. The U.S. Treasury, Bureau of Alcohol, Tobacco, and Firearms (BATE), now oversees the production, procurement, and use of ethanol in the United States. 

Completely Denatured Alcohol. Completely denatured alcohol (CD A) escapes the involved financial and administrative controls required of the other classifications of industrial ethanol. No tax is appHed, no bond is required, no permit is needed to enable a customer to purchase CD A. Requirements for records by both producer and user are minimal. These simplified regulations are possible because CDA is denatured with substances that render it totally unfit for beverage purposes. It is also unsuitable where odor is objectionable. CDA and products made from it are, however, governed by special labeling requirements of the BATE. Repackaging of completely denatured alcohol is permitted as long as labeling requirements are met. 

Proprietary Solvents and Special Industrial Solvents. Proprietary solvents and special industrial solvents are made with specially denatured alcohols according to the formulas authorized by the BATE. They can be purchased by customers without payment of tax, without posting a bond for tax, and without securing a permit from the BATE. SuppHers are required, however, to notify the BATE of the name, address, type of business, and approximate annual requirements and intended end use for any user buying in bulk. 

Specially Denatured Alcohol. Specially denatured alcohols (SDA) are formulations of ethanol containing denaturant substances that generally render them unfit for beverage use but do not limit their use in specified appHcations. To use a specially denatured alcohol, a manufacturer must apply to the BATE, giving quantitative formulas and processes. Specimen labels and a sample of the finished product are also required. Then, the prospective user must obtain a bond for the total amount of specially denatured alcohol on hand or in transit at any given time.

Frequently, ethanol that is not destined for human consumption is denatured by adding small quantities of methanol or benzene. This avoids the high federal tax on beverage alcohol denatured alcohol is poisonous.

When used in products not licensed for drinking, ethanol usually occurs in the form of denatured alcohol, or specially denatured alcohol—alcohol that has been rendered unfit for drinking. You will often see SD alcohol mentioned on a label, sometimes followed by a number and letter, such as 40-B. This is the designation given by the U.S. Bureau of Alcohol, Tobacco, and Firearms to the denaturing method used. For example, SD-40 is ethanol denatured by adding tiny amounts of the most bitter-tasting substance known denatonium benzoate. 

Denatonium benzoate is the bitterest-tasting substance known. It gets its name from denatured alcohol—alcohol that has been rendered unfit for drinking—and is often used in the denaturing process. Specially denatured alcohol 40, or SD-40, is ethanol that has been denatured by a tiny amount of denatonium benzoate. Denatonium benzoate is an ester of PABA, and is related to lidocaine, benzocaine, novocaine, and cocaine.

Biological oxidation of methanol and ethanol in the body produces the corresponding aldehyde followed by the acid. At times the alcoholics, by mistake, drink ethanol, mixed with methanol also called denatured alcohol. In the body, methanol is oxidised first to methanal and then to methanoic acid, which may cause blindness and death. A methanol poisoned patient is treated by giving intravenous infusions of diluted ethanol. The enz5mie responsible for oxidation of aldehyde (HCHO) to acid is swamped allowing time for kidneys to excrete methanol. 

If the contaminants exhibit a high vapor pressure, then they can be pumped out relatively quickly. If this is not successful, then the apparatus will have to be cleaned. Contaminated glass components will first be cleaned with chromic-sulfuric acid mixture or - if this is necessary - with dilute hydrofluoric acid (1 30). They are then rinsed with distilled water. If this does not bring about the desired results, then an organic solvent can be tried. Then the glass components will again have to be rinsed with methanol and distilled water. (Do not use denatured alcohol )... 

The strength of alcohol commonly used in the US is 95% (190 proof), while 96% is used in Europe. For prepn of perfumes the 70% alcobol is used. TTie so-called absolute alcobol (200 proof) is at least 99% and its use is restricted. to analytical purposes or research. The so-called industrial alcohol is unfit to drink because it contains up to 5% methanol (wood alcohol) or benzene. Such alcohol is known as denatured and it is briefly described in Vol 3 of Encycl, p D63-R. Denatured alcohol is used as a solvent for expls, rocket fuels, rubbers, detergents, etc. Mixture of 1 part alcobol with 2 parts eth (described in Vol 5 of Encycl as Diethyl Ether) used as a solvent in dehydration of Pyrocellulose in manuf of single-base propint, such as described in Davis (Ref 2) and also on p C399 of Vol 3 of Encycl, under "Colloiding Agents and Colloidal Propellants ...
